To all whom it may concern:

Be it known that I, CHARLES A. HARRIS, a citizen of the United States,residing at Webster City, in the county of Hamilton and State of Iowa,have invented a new and useful Safety-Shield and Self-Sharpener forRazors, of which cation.

The object of this invention is to provide an improved safety shield forrazors.

A further object of this invention is to provide an improved automaticSharpener for razors.

A further object of this invention is to provide an improved attachmentfor razors which will act as a combined safety shield and automaticSharpener for said razors.

A further object of this invention is to provide means for adjusting asafety shield attachment for razors.

My invention consists in the construction, arrangement and combinationof elements hereinafter set forth, pointed out in my claims andillust-rated by the accompanying drawing, in which- Figure 1 is a sideelevation of an ordinary razor showing my improved device attachedthereto in position for practical use, a portion of the handle beingbroken away to economize space. Fig. 2 is a side elevation opposite toFig. 1. Fig. 3 is an end view of the same, on an enlarged scale. Fig. 4:is a cross-section on the indicated line t--t of Fig. 1, also on anenlarged scale.

In the construction and mounting of the device as shown the numeral 1()designates the handle and 11 the blade of an ordinary razor. A bodyplate 12 is provided, and preferably is made of some light metal. Thelower portion 13 of the plate 12 is of approximately the same length asthe blade 11 of the razor, and lies parallel with and adjacent to thelower portion of said blade. The plate 12 is bent outwardly at an angleat 111 and is again bent at 15 and extends upwardly therefrom parallelwith the lower portion 13. The plate 12 also is bent at right angles at16 and extends laterally above the top of the blade 11 of the razor. Theupper portion of the plate 12 preferably is shorter than the lowerportion 13, as shown in Fig. 1. Spring arms 17, 18 are formed on or xedto the lateral portion of the following is a specithe plate 12 andextend downwardly thereblade 11 opposite to from on the side of the lthe lower portion 13 of said plate.

The spring arms 17, 18 are bent inwardly and are adapted to pressagainst the blade 11 and hold the device in intimate Contact therewith.Ears 19, 2O are formed on or xed to end portions of the lower portion 13of the plate 12 and extend downwardly therefrom. The ears 19, 2O areapertured and carry a roller 21 mounted for rotation between said earsand below the plate 12. The roller 21 preferably is composed of hardenedsteel or some composition for sharpening, and is adapted to roll againstthe edge of the blade 11. The upper lateral portion of the plate 12 isprovided with a threaded aperture, and a thumb screw 22 is mountedtherein. The lower end portion of the thumb screw 22 is adapted to bearagainst the top of the blade 11, thus providing means for adjusting thedevice relative to said blade.

In the practical use of this device the attachment is placed in positionby slipping it over the end of the blade 11, the spring arms 17 18engaging the side of the blade and holding the device in position. rI hedevice is adjusted by means of the thumb screw 22 so that the lowerportion of the roller 21 projects a slight distance below the edge ofthe blade 11, as shown inthe drawing. The razor may then be used in theordinary manner, the. roller 21 being on the side thereof away from thesurface being shaved. The roller 21 acts as a shield or safety devicefor the edge of the blade 11, since any tilting of said blade whichordinarily would cause it to cut theV skin will bring the roller 21 intocontact with the cuticle and prevent cutting thereof. The roller 21 alsoprevents the edge of the blade 11 being brought into cutting contactwith any projection on the surface being shaved. During most of theoperation of sha-ving the roller 21 will be caused to roll in itsbearings, either through contact with the face or by The use of thisdevice will afford convenience, comfort and safety to those who preferthe ordinary razor to the usual `t'orms of safety razors, and will in nowise intertere with the gliding or diagonal stroke commonly employed inthe use of the ordinary razor.` It may be attached to any razor of theordinary type, which differ widely in siz'e, and may be quickly andreadily adjusted by means of the thumb screw 22.

claim as my invention` l. The combination with a razor having anordinary blade, of a safety shield shaped and arranged for longitudinalmovement on and removal and replacement relative to saidblade, saidsafety shield also adapted for lateral adjustment on said blade, saidplate of approximately .the same length as the blade and adapted forContact with either side thereof, one margin of said plate beingcontiguous to the cutting edge of the blade, said plate oiset away fromsaid blade and formed with an inwardly projecting rear portion extendingacross the back ot' the blade and spaced therefrom, said plate alsoformed with spring arms integral with and extending at right angles fromthe free margin of the laterally extending rear portion of the plate andsprung outward relative to said blade between their ends, the free endsof said spring' arms adapted to engage the blade 1n opposition to theplate, said plate formed with a screw7 seat in the center ot' itslaterally extending rear portion, an adjusting screw screwed throughsaid seat and adapted to engage the back of the blade, said plate alsoformed with ears on its ends outstanding from the plane ot' the plate,and a roller journaled at its ends in said ears and adapted to projectbeyond and in contact with the cutting edge of the blade,

said roller being spaced from the foremost margin of the plate.
